My son and I are disappointed that the harness does not do what its stated purpose is. It is to be a no-pull harness and it is not. The thirty-pound dog still pulls hard. So I think this harness is a failure in its mission to be a no-pull harness. Also, my dog was just crying because his arm was caught under the belt. He needed me to get him loose. I had initially complained about the belt's looseness since it does not hold tight and the adjustment does not hold. I was not given a refund or a replacement. rejected User's recommendation: Not a good fit for dogs. I would not recommend buying this harness. Its advertisement is very over rated. Very disappointed at both the concern by the company after purchasing it and the product itself.
